Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 11,160,215, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 11,160,215 | |
| -1 | -11,160,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,160,215.
Example:
1 x 11,160,215 = 11,160,215
and
-1 x -11,160,215 = 11,160,215
Notice both answers equal 11,160,215
With that explanation out of the way, let's continue. Next, we take the number 11,160,215 and divide it by 2:
11,160,215 ÷ 2 = 5,580,107.5
If the quotient is a whole number, then 2 and 5,580,107.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,160,215 | |
| -1 | -11,160,215 |
Now, we try dividing 11,160,215 by 3:
11,160,215 ÷ 3 = 3,720,071.6667
If the quotient is a whole number, then 3 and 3,720,071.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,160,215 | |
| -1 | -11,160,215 |
Let's try dividing by 4:
11,160,215 ÷ 4 = 2,790,053.75
If the quotient is a whole number, then 4 and 2,790,053.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 11,160,215 | |
| -1 | 11,160,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 6,997 | 34,985 | 76,967 | 202,913 | 384,835 | 1,014,565 | 2,232,043 | 11,160,215 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -6,997 | -34,985 | -76,967 | -202,913 | -384,835 | -1,014,565 | -2,232,043 | -11,160,215 |
